blk-settings: round down io_opt to physical_block_size
There was a bug report [1] where the user got a warning alignment
inconsistency. The user has optimal I/O 16776704 (0xFFFE00) and physical
block size 4096. Note that the optimal I/O size may be set by the DMA
engines or SCSI controllers and they have no knowledge about the disks
attached to them, so the situation with optimal I/O not aligned to
physical block size may happen.
This commit makes blk_validate_limits round down optimal I/O size to the
physical block size of the block device.
